The much-talked-about British documentary on Michael Jackson — airing Thursday on ABC as part of a special two-hour 20/20 — is apparently going to live up to all the hype. Among the revelations Jacko reportedly makes: He once slept in the same bed as Macaulay Culkin and his brother Kieran; his terrace-dangled infant son, Prince Michael II, was conceived by a surrogate mother whom he had never met; and he underwent two operations on his nose because "it helped me breathe better so I can hit higher notes." His best quote from the documentary? That's easy: "If there were no children on this Earth, if someone announced all kids were dead, I would jump off the balcony immediately."
